ATLANTA — Tre Mason rushed for 304 yards and four touchdowns, leading No. 3 Auburn to a wild 59-42 victory over No. 5 Missouri in a Southeastern Conference title showdown Saturday that looked more like a video game.

Auburn (12-1) kept alive its hopes of playing for the national championship, though the Tigers needed either top-ranked Florida State or No. 2 Ohio State to lose in their respective conference title games.

“We deserve it,” receiver Sammie Coates said. “We won the SEC championship. What else do you want us to do?”

If Auburn misses out on the BCS title game, it will head to the Sugar Bowl as the SEC champion. Missouri (11-2) should be in the mix for a New Year’s Day bowl, with the Capital One, Cotton and Outback games among the possible destinations.

Auburn set an SEC championship game record with 677 yards, including 545 on the ground. Mason had scoring runs of 7, 3 and 1 yards before bursting up the middle on a 13-yard TD that clinched the victory with 4:22 remaining. He carried the ball a staggering 46 times, an easy choice as the game’s MVP. He even struck a Heisman pose, his longshot candidacy getting a huge boost.

“You’re looking at one of the top running backs in college football,” coach Gus Malzahn said. “He was a warrior today. Unbelievable.”
